It is the eve of April 1, that is, April Fool's Day. For the Louds is the worst day because of Luan.
Lincoln brings together all the food and video games that can.
"Lincoln, why all the fuss? It's just a prank day. " As said.
"Yes, but for us it's the worst day ever. Luan is playing some really horrible pranks. You are really lucky that you stayed in hiding. "Lincoln said to his Kwami.
As hears footsteps coming towards Lincoln's room and hides.
"Lincoln, now is not the time to talk to yourself. We must prepare! "Lynn Jr said.
"I wasn't talking to myself, I was just saying my thoughts out loud. "
Binoculars are wrapped in bubble wrap.
"Quick, put it on again. I want to be safe. "Lola said to Lana.
The tomboy girl wraps her twin sister even more bubble wrap.
Everyone prepares in their own way. Suddenly Luan goes upstairs.
"Hello to my family. Tomorrow will be April Fool's Day and hopefully you will be ready because it will be so much fun. "The ponytail girl said. She blows a bubble on Lola's bubble wrap.
His family is terrified.
"I think I need to change my underwear."
Lincoln returns to his room with the provisions.
"Ok, I understand better why you are afraid of her. But you never thought about asking for an order? "
"Well..."
Flashback.
It was April Fool's Day last year. Lori was waiting for Bobbie to visit to help her with a project
"Luan, you have to cancel your pranks! Bobby has to come and help me with a school project and I don't want him to be the victim of your pranks. " Lori begs her little sister.
"Hmmm ... Ok."
"Truly? Thanks Luan. You are ... "The blonde girl receives a pie in the face and white flour falls on her with clown make-up.
"Ahhh !"
"I got you!" She laughs.
Lori is angry and she has to cancel.
End of flashback.
"Your sister is really nuts. "
"That's why I prefer to stay in the room all day, tomorrow."
"What a pity you can't lock him up. "As said.
"Lock him up ... Lock up ... Sure. As, you had a great idea!"
Luan is locked in the cage in the basement.
"It's not fair! It's day is supposed to be too much." Luan is angry at being locked up by his family.
His frustration is felt by Hawk Moth. A black butterfly arrives in the basement through the window and fits into the flower on Luan's pajamas.
{The Joker, I'm Hawk Moth. Your family keeps you from having fun on your favorite day, but I give you the power to make more fun jokes. In return, you must bring me the miraculous!}
Hawk Moth shows mental images of Ladybug's Miraculous, Cat Noir, and Ace King.
"It'll be miraculously fun, you get it? Amusing? Miraculously? "
{Bring me their jewelry.}
A black smoke surrounds him, Luan becomes the ugly version of his superhero doppelganger. Black smoke invades the Loud House to transform it into an inflatable fun house.
The next morning. Lincoln and As wake up.
Lincoln and As wake up.
"Good morning, Lincoln."
"Good morning, As. Today is April Fool's Day. What do you want to do? "
"I would do..."
Lori: Ahhhh! My eyebrows!
"It's your sister? "
"Weird, Lori always screams like that when Luan's pranks ..."
Ace is hiding in the closet of Lincoln's sweater. The white haired boy comes out of his room and seeing his whole house is different.
Maison Loud has become like a bouncy castle. Inside there are several doors.
"Who arrived at the house? "Lincoln tries a door.
"Lincoln, don't open the door!"
"What?" Upon opening the door, Lincoln receives three cream pies in the face.
He tries to go to the bathroom but the door is trapped and monkeys fall on him.
"Ahhh!"
"Lori, what's going on? Why is the house like this? "
"I don't know? When I woke up the house was like this and I couldn't find the others. "
Suddenly a huge balloon clown head appeared. The balloon clown swallows Lori and locks her in a giant dog-shaped balloon.
The clown tries to swallow Lincoln. Lincoln runs away and hides in a gift box.
"I think your sister has turned into a naughty one. "
"Hawk Moth managed to make the prank day really worse. Let's Play! "
Lincoln transforms into the Ace of King.
"I hope Ladybug will come. I will need some backup."
Ace of King comes out of its hiding place. Balloon animals attack him. He destroys them with his playing cards.
He goes in search of all his family and comes across the villain in his room, behind her he has a big TV screen.
Luan as his alter ego Joker.
"We have a special guest. Strange I don't remember inviting you, whatever. Everyone who enters the house will be prey to my jokes. "
"Luan, where did our… I mean the Loud family? "
"The Loud family? They taste their own medicine for locking me up. "
The screen shows the Loud family encasing balloons in various animal shapes. Everyone laughs Non Stop and are out of breath.
"Free them!"
"No way. It's a prank day and it's supposed to be fun. Especially for me. " The Joker laughs.
Ace de Roi tries to stop him but the villain escapes with his pepper bombs.
"I really need backup."
He checks each of the traps in the house and undergoes each of the pranks, one after the other.
"Do not worry. I promise to find you. "
Outside. Marinette makes a delivery. She delivers a cake to Mr. Grosse.
"Finally my order arrived. Thank you. "
"You're welcome. "The girl with the blue hair was about to enter her house but seeing the house next door looks really strange. "Is this the Loud house?"
"Is it weird buying a bouncy house? "Tikki finds that weird.
"I don't think they bought this."
Marinette approaches the house and looks out the window, seeing Ace of Kings inside.
"If As is there, it means Hawk Moth has made another victim. "
"You're right. Tikki, Spot on! " She transforms into Ladybug and goes through the front door.
In the house, Ace de Roi continues to search for his family.
"Where are they? I have looked at every trap in the house."
"Need help? "
"Ladybug, I'm glad you came. My sister ... Luan Loud has turned into a villain. "
"And was she the one who also transformed the house like that?"
"Right. And we also have to save the Loud family."
"Yes."
The two proceed by eliminating the doors they visited and there would remain the one in the basement.
The two heroes go downstairs, to arrive at a circus tent.
"Another surprise visit? I am spoiled today. "
{The Joker, get their Miraculous!}
"Hawk Moth, want your magic jewelry. Give it to me!"
She sends hordes of balloon animals at them. Ace and Ladybug destroy them.
Their number is decreasing.
"Lucky Charme!" Her power spawns a gift package. "How can I use this?"
"Full Deck!" Her special power is called Princess Diamond.
The superhero version of Lola. The princess in pink, throws her tiara like a boomerang.
The object blows up all the balls that Loud's family is trapped in.
The ladybug girl knows how to use the item. She uses the classic gift prank.
"Joker. I'll give you my Miraculous. "
"Did you understand that you didn't have a chance like me?"
"Yes. My jewelry is in the box. "
Joker takes the gift package and opens it and gets pepper in his face. Joker can't stop sneezing.
"Pepper? Sneeze! Sneeze! Sneeze! "
"Maybe the Akuma is in bloom?" He arranges the flower and destroys it.
The black butterfly is captured by Ladybug, then purified.
"Miraculous Ladybug !" Millions of ladybugs rearrange the house, which is as it was before.
Lincoln's family appeared in the living room.
"That happened? "
"Pound it!"
This whole event had taken up the entire April Fool's Day, now the party is over.
"I am glad that everything is well finished. "He said. But while walking, he slips on a banana peel.
"I don't think it's over yet. "
